GLASS NEGATIVES TYPE IDENTIFICATION

 Early Photographers might use the knowledge and talents from their profession to naturally expand their interest in the expanding world of photography. That is why you will find opticians, jewelers, physicians, dentists, apothecaries, and scientists associated with the practice. Opticians worked with eyesight and eye glasses for correction so their knowledge would expand the development of camera lenses, glass negatives and the science of light exposure.

EXAMPLES OF GLASS NEGATIVE COMPANIES SELLING BOXED DRY PLATES

From The Sun Journal, Lewiston, Maine:

The Standard Dry Plate Company, has been organized in Lewiston (Maine) with H. C. Ross, president, C. W. Curtis, treasurer, C. W. Curtis, H. C. Ross, and N. C. Dinsmore, directors. The capital stock is fixed at $50,000 of which $10,000 is paid in. The objects of the corporation are to manufacture and sell at wholesale and retail Dry plates for the photographic business, and also to deal in supplies for this business.

M. A. SEED DRY PLATE COMPANY, 2005 Locust  ST. LOUIS. MISSOURI (1882-1902).

Miles Ainscough Seed (1843 - 1913) 

Manufacturer. Born in Preston, England, Seed became interested in photography and studied the sciences and continued to do research in physics, astronomy, and chemistry and to experiment particularly with different processes for making and developing photographic plates. Believing that better opportunities were to be found in America for applying the results of his experiments, he emigrated to the United States in 1865 and settled in St. Louis, Missouri where he obtained a position in the photographic gallery of John Scholton. He soon became the chief operator and manager and continued in this work for many years, devoting his spare time to further experiments at his home to simplify the process that he had developed for producing photographic negatives. After several years of persistent effort he perfected a process for the manufacture of a photographic dry plate which appeared so promising a contribution to photography that, with the financial help of friends, he formed the M.A. Seed Dry Plate Company in St. Louis in 1882 and began to manufacture his new product. In ten years he not only manufactured dry plates but also produced celluloid films for negatives and introduced positive celluloid films, lantern slides, and double-coated non-inhalation plates. His dry plate was the first one sensitive enough to be used for X-ray purposes and astronomical pictures. As a result, a larger market was opened up to the product of Seed's company and it expanded at a rapid rate. In 1902 he sold the business as well as his formulas to the Eastman Kodak Company in Rochester, New York and for the next five years, he was employed by them as a special advisor to the firm.
